Experimental Assessment of Carbon Dioxide Content in Inhaled Air With or Without Face Masks in Healthy Children

Results

The mean (SD) age of the children was 10.7 (2.6) years (range, 6-17 years), and there were 20 girls and 25 boys. Measurement results are presented in the Table. We checked potential associations with outcome. Only age was associated with carbon dioxide content in inhaled air (y = 1.9867 – 0.0555 × x; r = –0.39; P = .008; Figure). Hence, we added age as a continuous covariate to the model. This revealed an association (partial η2 = 0.43; P < .001). Contrasts showed that this was attributable to the difference between the baseline value and the values of both masks jointly. Contrasts between the 2 types of masks were not significant. We measured means (SDs) between 13 120 (384) and 13 910 (374) ppm of carbon dioxide in inhaled air under surgical and filtering facepiece 2 (FFP2) masks, which is higher than what is already deemed unacceptable by the German Federal Environmental Office by a factor of 6.This was a value reached after 3 minutes of measurement.Children under normal conditions in schools wear such masks for a mean of 270 (interquartile range, 120-390) minutes.3 The Figure shows that the value of the child with the lowest carbon dioxide level was 3-fold greater than the limit of 0.2 % by volume.4 The youngest children had the highest values, with one 7-year-old child’s carbon dioxide level measured at 25 000 ppm.

COVID-19 might be over,but viral infections in Israel are surging

Children and adults around the country are getting sick as it usually happens in the winter, experts say.

The corona crisis might be over, but all over Israel adults and children are getting sick with viral infections in a phenomenon that is unprecedented for this time of the year, according to several medical professionals.

“We have never seen anything like this,”said Dr. Tal Brosh, head of Infectious Disease Unit at the Samson Assuta Ashdod Hospital. “We’ve been monitoring viral infections in the hospital, which of course is just the tip of the iceberg of what is going on in the community, as for each hospitalized patient, there are many more out there. Since the spring, we have been seeing an increasing number of respiratory diseases, and since May there has been a surge in RSV cases.”

…

All experts agreed that nobody can predict how this surge of infections will continue to behave in the coming weeks and months.

“This is not a pandemic, these viruses exist in the country and every winter comes with illnesses,” Brosh said. “What is weird now is the season, and we do not know whether this will die soonor continue into next winter, and what will actually happen next winter.”
